This is in-depth account of Porth yr Ogof and the adjacent caves and karst.
There are also reproductions of old engravings of Porth yr Ogof.

This cave is situated in a beautiful and secluded river valley. By descending a
rough footpath, one arrives at the cave entrance, an impressive gorge 60 feet
deep, with a low wide entrance at the bottom.

Visitors are recommended to carry an electric torch and wear strong boots.

After entering the cave, walking straight ahead, a wide, deep pool of water is
reached.
Once one's eyes have become accustomed to the light, it is possible to see the
outline of what looks very much like a white horse on the opposite side of the
pool.
This is in fact a vein of calcite in the rock, which has been so worn as to look
like a horse and which gives the cave its alternative name.

The cave actually goes under the road, and by crossing the road, passing through
the gate and following the track, past several more entrances to the cave, it is
possible to come to the resurgence.
Here there is a wide grassy meadow, ideal for picnics, and a natural swimming
pool in the river.
This is a most idyilic spot, and understandably popular at weekends and bank
holidays with cavers, hikers and campers.

2003 update.
There is now a large car park, toilets and screened off changing areas for both
male and female visitors.
In the summer there is a charge of £3.00 for cars and £8.00 for
minibuses, for parking.
There are some improvements in the form of pathways and railings but the descent
to the cave is still very rough.
Good walking boots are needed.
Since 1972 six people have drowned in the resurgence pool.
Because of this I recommend that visitors do not enter the cave, but stick to
the foot paths.
